EC5645ETTTS-50.000M TR

Oscillators Overview

The EC5645ETTTS-50.000M TR is a standard quartz crystal oscillator (SPXO) manufactured by Ecliptek, operating at a nominal frequency of 50 MHz. It utilizes an LVCMOS output format and requires a 3.3 Vdc supply voltage with ±10% tolerance. The device features a 4-pad ceramic surface-mount package measuring 2.0 mm x 2.5 mm. Frequency stability is rated at ±50 ppm across the full operating temperature range of -40°C to +85°C, inclusive of calibration tolerance, temperature drift, voltage changes, load variations, first-year aging, shock, and vibration. Maximum supply current is 7 mA, while standby current in tri-state mode is 10 μA. RMS phase jitter within the 12 kHz to 20 MHz offset range is limited to 1 ps.

Oscillators Feature Summary

• Integrated tri-state control on Pin 1 for enable/disable functionality, allowing high-impedance standby mode to reduce power consumption.
• Full industrial-grade frequency stability specification that accounts for all environmental and operational stress factors including temperature, voltage, and mechanical shock.
• RoHS compliant construction using lead-free materials, ensuring adherence to environmental regulations for global deployment.

Oscillators Applications

• Industrial gateway reference clock sources
• High-speed Ethernet MAC interface timing
• Battery-powered portable industrial equipment
• ADC sampling clock generation

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Ecliptek or Abracon, as both entities are associated with this product line. Ensure the requested frequency matches the 50.000 MHz requirement exactly, as other frequencies in the series exist. Check RoHS compliance documentation if required for specific regulatory audits.

Oscillators Selection Notes

Select this component for applications requiring a compact 2.0x2.5 mm footprint with strict low-power constraints. The 1 ps jitter performance supports high-speed digital interfaces like Gigabit Ethernet. The wide input voltage tolerance of ±10% accommodates fluctuating power rails common in industrial environments without additional regulation.

Oscillators Part Context

This part belongs to the EC5645 ET series of ceramic SMD oscillators. The series offers various frequencies and package sizes, ranging from 2.0x2.5 mm to larger footprints. The EC5645 variant specifically targets space-constrained designs while maintaining industrial temperature ranges and robust electrical specifications comparable to larger packages.

Oscillators Replacement Considerations

Direct substitutes include other EC5645ETTTS variants with different frequencies, such as EC5645ETTTS-30.000M TR or EC5645ETTTS-14.31818M TR, provided the frequency difference is acceptable. Cross-brand replacements require matching the 2.0x2.5 mm package, 3.3V supply, LVCMOS output, and ±50 ppm stability metrics.
